Open Source, Operators Key to ONF’s New Optical Disaggregation Plan
The ODTN project has some overlap with OpenConfig and TIP, but differs from the AT&T-led OpenROADM project.
Blessay: A Taxonomy for Five levels of Intent Based Networking
In my view, Intent Based Networking (IBN) is going to be journey. Its not a specific thing like ‘routing’ or ‘traffic shaping’. Its not a product or a feature, its group of technologies. In the same way that Software Defined Networking is a broad definition. I think I can see a way to classify how […]
Sharing more Details, not more Data: Our new Privacy Policy and Data Protection Plans
After an exhilarating first month as Cloudflare’s first Data Protection Officer (DPO), I’m excited to announce that today we are launching a new Privacy Policy. Our new policy explains the kind of information we collect, from whom we collect it, and how we use it in a more transparent way. We also provide clearer instructions for how you, our users, can exercise your data subject rights. Importantly, nothing in our privacy policy changes the level of privacy protection for your information.
Our new policy is a key milestone in our GDPR readiness journey, and it goes into effect on May 25 — the same day as the GDPR. (You can learn more about the European Union’s General Data Protection Regulation here.) But our GDPR journey doesn’t end on May 25.
Over the coming months, we’ll be following GDPR-related developments, providing you periodic updates about what we learn, and adapting our approach as needed. And I’ll continue to focus on GDPR compliance efforts, including coordinating our responses to data subject requests for information about how their data is being handled, evaluating the privacy impact of new products and services on our users’ personal data, and working with customers who want Continue reading
Cisco’s IoT, Collaboration Head Rowan Trollope Exits to Join Cloud Startup as CEO
The news of Trollope's departure comes as Cisco announced its intent to acquire AI startup Accompany. Cisco appointed Accompany's CEO and founder Amy Chang as SVP of its Collaboration group.
Expanding Multi-User Access on dash.cloudflare.com
One of the most common feature requests we get is to allow customers to share account access. This has been supported at our Enterprise level of service, but is now being extended to all customers. Starting today, users can go to the new home of Cloudflare’s Dashboard at dash.cloudflare.com. Upon login, users will see the redesigned account experience. Now users can manage all of their account level settings and features in a more streamlined UI.

All customers now have the ability to invite others to manage their account as Administrators. They can do this from the ‘Members’ tab in the new Account area on the Cloudflare dashboard. Invited Administrators have full control over the account except for managing members and changing billing information.
For Customers who belong to multiple accounts (previously known as organizations), the first thing they will see is an account selector. This allows easy searching and selection between accounts. Additionally, there is a zone selector for searching through zones across all accounts. Enterprise customers still have access to the same roles as before with the addition of the Administrator and Billing Roles.
The New Dashboard @ dash. Continue reading
Datanauts 132: Unit Testing For Fun And Profit
While performing a routine sensor sweep of the Gargleblaster nebula, the crew of the Datanauts starship noticed that many of the tasks are manual in nature and could, with a little effort, be automated with some scripting.
However, every time we moved on from one part of the nebula to another, a different error would crop up with the script s code. Isn t there some way that we can automatically test our code to make sure that more time is spent drinking a frothy ale instead of all this debugging?
On today’s episode with talk with Adam Bertram, a Microsoft MVP and author of The Pester Book.
He is currently a Senior Systems Automation Engineer working with PowerShell, Desired State Configuration, and various other DevOps tools to coordinate reliable software deployments for a biotech company. You can find his work at adamtheautomator.com.
We start by defining a unit test for scripts, and how unit testing differs from integration, functional, regression tests, and others.
Then we dive into why you’d want to test your scripts (testing isn’t just for developers!), and how to create these tests.
We also talk about the notion of test-driven development, and dive Continue reading
The State of Broadband Connectivity in Canada’s Rural and Remote Regions
In April, the Canadian Standing Committee on Industry, Science, and Technology presented the “Broadband Connectivity in Rural Canada: Overcoming the Digital Divide” to the House of Commons in order to make public their findings and recommendations from a study on broadband connectivity. (In May 2016, the committee adopted a motion to do a study on broadband connectivity, with the primary purpose of developing a plan to improve rural broadband and demonstrate the Internet’s effect on rural economies.) To create the report, the committee used information and conversations from seven meetings, as well as 50 oral and written submissions. Participants in this process represented businesses, small and large service providers, experts, and on-the-ground rural providers. The Internet Society applauds the committee’s use of a consultative process and its effort to provide concrete recommendations to the House of Commons to connect Canada’s rural and remote citizens.
In 2016, the Canadian Radio-television and Telecommunications (CRTC) declared Internet access an essential service and set the minimum performance standard at 50 Mbps download and 10 Mbps upload. At the same time, it estimated that it will take between 10 and 15 years for the remaining 18% of Canadians to reach those Continue reading
Update: Automatic EVPN Route Targets in EBGP Environments
After I posted the EVPN Route Target Considerations section of BGP in Data Center Fabrics document Lukas Krattiger pointed out another option available with Cisco Nexus-OS: it can rewrite ASN portion of EVPN Route Target in incoming EBGP updates. Updated version of the affected section is already online.
Andromeda: performance, isolation, and velocity at scale in cloud network virtualization
Andromeda: performance, isolation, and velocity at scale in cloud network virtualization Dalton et al., NSDI’18
Yesterday we took a look at the Microsoft Azure networking stack, today it’s the turn of the Google Cloud Platform. (It’s a very handy coincidence to have two such experience and system design report papers appearing side by side so that we can compare). Andromeda has similar design goals to AccelNet: performance close to hardware, serviceability, and the flexibility and velocity of a software-based architecture. The Google team solve those challenges in a very different way though, being prepared to make use of host cores (which you’ll recall the Azure team wanted to avoid).
We opted for a high-performance software-based architecture instead of a hardware-only solution like SR-IOV because software enables flexible, high-velocity feature deployment… Andromeda consumes a few percent of the CPU and memory on-host. One physical CPU core is reserved for the Andromeda dataplane… In the future, we plan to increase the dataplane CPU reservation to two physical cores on newer hosts with faster physical NICs and more CPU cores in order to improve VM network throughput.
High-level design
Both the control plane and data plane use a hierarchical structure. The control Continue reading
